This invention is directed to hexahydro-cycloheptapyrazole cannabinoid (CB) modulator compounds and a method for use in treating, ameliorating or preventing a cannabinoid receptor mediated syndrome, disorder or disease.

BACKGROUND OF THE INVENTION

Before the discovery of the cannabinoid CB1 and CB2 receptors, the term cannabinoid was used to describe the biologically active components of cannabis sativa, the most abundant of which are delta-9-tetrahydrocannabinol (THC) and cannabidiol.

THC is a moderately potent partial agonist of the CB1 and CB2 receptors and is considered the “classical cannabinoid,” a term now used to refer to other analogues and derivatives that are structurally related to the tricyclic dibenzopyran THC core. The term “nonclassical cannabinoid” refers to cannabinoid agonists structurally related to cannabidiol.

Pharmacological investigations have concentrated on selective CB receptor modulators of the pyrazole structural class, which include SR 141716A (the monohydrochloride salt of SR 141716) and SR 144528.

Pyrazole cannabinoid modulators are one among the many different structural classes which have aided the development of CB pharmacology, have helped to determine the biological effects mediated by the cannabinoid receptors, will lead to further refinement of current compounds and will be a source of new chemical classes in the future.

Certain compounds (including SR 141716, SR 144528 and the like) that were originally classified as selective antagonists are now considered to act as “inverse agonists” rather than pure antagonists. Inverse agonists have the ability to decrease the constitutive level of receptor activation in the absence of an agonist instead of only blocking the activation induced by agonist binding at the receptor. The constitutive activity of CB receptors has important implications since there is a level of continuous signaling by both CB1 and CB2 even in the absence of an agonist. For example, SR 141716A increases CB1 protein levels and sensitizes cells toward agonist action, thus indicating that inverse agonists may be another class of ligands used to modulate the endocannabinoid system and the downstream signaling pathways activated by CB receptors.

PCT Application WO2006/030124 describes pyrazole derivatives as CB1 or CB2 receptor agonists.

Advances in the synthesis of CB and cannabimimetic ligands have furthered the development of receptor pharmacology and provided evidence for the existence of additional cannabinoid receptor sub-types. However, there remains an ongoing need for the identification and development of CB1 or CB2 receptor cannabinoid modulators for the treatment of a variety of CB receptor modulated syndromes, disorders and diseases.

Furthermore when the compounds of the present invention carry an acidic moiety, suitable pharmaceutically acceptable salts thereof may include alkali metal salts, e.g. sodium or potassium salts; alkaline earth metal salts, e.g. calcium or magnesium salts; and salts formed with suitable organic ligands, e.g. quaternary ammonium salts. Thus, representative pharmaceutically acceptable salts include the following: acetate, benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, calcium, camsylate (or camphorsulphonate), carbonate, chloride, clavulanate, citrate, dihydrochloride, edetate, fumarate, gluconate, glutamate, hydrabamine, hydrobromine, hydrochloride, iodide, isothionate, lactate, malate, maleate, mandelate, mesylate, nitrate, oleate, pamoate, palmitate, phosphate/diphosphate, salicylate, stearate, sulfate, succinate, tartrate, tosylate.

The present invention includes within its scope prodrugs and metabolites of the compounds of this invention. In general, such prodrugs and metabolites will be functional derivatives of the compounds that are readily convertible in vivo into an active compound.

Thus, in the methods of treatment of the present invention, the term “administering” shall encompass the means for treating, ameliorating or preventing a syndrome, disorder or disease described herein with a compound specifically disclosed or a compound, or prodrug or metabolite thereof, which would obviously be included within the scope of the invention albeit not specifically disclosed for certain of the instant compounds.

The term “prodrug” means a pharmaceutically acceptable form of a functional derivative of a compound of the invention (or a salt thereof), wherein the prodrug may be: 1) a relatively active precursor which converts in vivo to an active prodrug component; 2) a relatively inactive precursor which converts in vivo to an active prodrug component; or 3) a relatively less active component of the compound that contributes to therapeutic biological activity after becoming available in vivo (i.e., as a metabolite). Conventional procedures for the selection and preparation of suitable prodrug derivatives are described in, for example, “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.

The term “metabolite” means a pharmaceutically acceptable form of a metabolic derivative of a compound of the invention (or a salt thereof), wherein the derivative is a relatively less active component of the compound that contributes to therapeutic biological activity after becoming available in vivo.

The present invention contemplates compounds of various isomers and mixtures thereof. The term “isomer” refers to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. Such substances have the same number and kind of atoms but differ in structure. The structural difference may be in constitution (geometric isomers) or in an ability to rotate the plane of polarized light (stereoisomers).

The term “stereoisomer” refers to isomers of identical constitution that differ in the arrangement of their atoms in space. Enantiomers and diastereomers are stereoisomers wherein an asymmetrically substituted carbon atom acts as a chiral center. The term “chiral” refers to a molecule that is not superposable on its mirror image, implying the absence of an axis and a plane or center of symmetry. The term “enantiomer” refers to one of a pair of molecular species that are mirror images of each other and are not superposable. The term “diastereomer” refers to stereoisomers that are not related as mirror images. The symbols “R” and “S” represent the configuration of substituents around a chiral carbon atom(s). The symbols “R*” and “S*” denote the relative configurations of substituents around a chiral carbon atom(s).

The term “racemate” or “racemic mixture” refers to a compound of equimolar quantities of two enantiomeric species, wherein the compound is devoid of optical activity. The term “optical activity” refers to the degree to which a chiral molecule or nonracemic mixture of chiral molecules rotates the plane of polarized light.

The term “geometric isomer” refers to isomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a cycloalkyl ring or to a bridged bicyclic system. Substituent atoms (other than H) on each side of a carbon-carbon double bond may be in an E or Z configuration. In the “E” (opposite sided) or “chair” configuration, the substituents are on opposite sides in relationship to the carbon-carbon double bond; in the “Z” (same sided) or “boat” configuration, the substituents are oriented on the same side in relationship to the carbon-carbon double bond. Substituent atoms (other than H) attached to a carbocyclic ring may be in a cis or trans configuration. In the “cis” configuration, the substituents are on the same side in relationship to the plane of the ring; in the “trans” configuration, the substituents are on opposite sides in relationship to the plane of the ring. Compounds having a mixture of “cis” and “trans” species are designated “cis/trans”. Substituent atoms (other than H) attached to a bridged bicyclic system may be in an “endo” or “exo” configuration. In the “endo” configuration, the substituents attached to a bridge (not a bridgehead) point toward the larger of the two remaining bridges; in the “exo” configuration, the substituents attached to a bridge point toward the smaller of the two remaining bridges.

It is to be understood that the various substituent stereoisomers, geometric isomers and mixtures thereof used to prepare compounds of the present invention are either commercially available, can be prepared synthetically from commercially available starting materials or can be prepared as isomeric mixtures and then obtained as resolved isomers using techniques well-known to those of ordinary skill in the art.

The isomeric descriptors “R,” “S,” “S*,” “R*,” “E,” “Z,” “cis,” “trans,” “exo” and “endo” are used as described herein for indicating atom configuration(s) relative to a core molecule and are intended to be used as defined in the literature (IUPAC Recommendations for Fundamental Stereochemistry (Section E), Pure Appl. Chem., 1976, 45:13-30).

The compounds of the present invention may be prepared as individual isomers by either isomer-specific synthesis or resolved from an isomeric mixture. Conventional resolution techniques include forming the free base of each isomer of an isomeric pair using an optically active salt (followed by fractional crystallization and regeneration of the free base), forming an ester or amide of each of the isomers of an isomeric pair (followed by chromatographic separation and removal of the chiral auxiliary) or resolving an isomeric mixture of either a starting material or a final product using preparative TLC (thin layer chromatography) or a chiral HPLC column.

Furthermore, compounds of the present invention may have one or more polymorph or amorphous crystalline forms and as such are intended to be included in the scope of the invention. In addition, some of the compounds may form solvates with water (i.e., hydrates) or common organic solvents, and such are also intended to be encompassed within the scope of this invention.

During any of the processes for preparation of the compounds of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, ed. J. F. W. McOmie, Plenum Press, 1973; and T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991. The protecting groups may be removed at a convenient subsequent stage using methods known in the art.

Therapeutic Use

CB1 and CB2 cannabinoid receptors belong to the G-protein-coupled receptor (GCPR) family, a receptor super-family with a distinctive pattern of seven transmembrane domains, which inhibits N-type calcium channels and/or adenylate cyclase to inhibit Q-type calcium channels.

CB1 receptors are present in the CNS, predominately expressed in brain regions associated with memory and movement such as the hippocampus (memory storage), cerebellum (coordination of motor function, posture and balance), basal ganglia (movement control), hypothalamus (thermal regulation, neuroendocrine release, appetite), spinal cord (nociception), cerebral cortex (emesis) and periphery regions such as lymphoid organs (cell mediated and innate immunity), vascular smooth muscle cells (blood pressure), gastrointestinal tract (innate antiinflammatory in the tract and in the esophagus, duodenum, jejunum, ileum and colon, controlling esophageal and gastrointestinal motility), lung smooth muscle cells (bronchodilation), eye ciliary body (intraocular pressure).

CB2 receptors appear to be primarily expressed peripherally in lymphoid tissue (cell mediated and innate immunity), peripheral nerve terminals (peripheral nervous system), spleen immune cells (immune system modulation) and retina (intraocular pressure). CB2 mRNA is found in the CNS in cerebellar granule cells (coordinating motor function).

Pharmacological and physiological evidence also suggests that there may be other cannabinoid receptor subtypes that have yet to be cloned and characterized.

Where activation or inhibition of a CB receptor appears to mediate various syndromes, disorders or diseases, potential areas of clinical application include, but are not limited to, controlling appetite, regulating metabolism, diabetes, reducing glaucoma-associated intraocular pressure, treating social and mood disorders, treating seizure-related disorders, treating substance abuse disorders, enhancing learning, cognition and memory, controlling organ contraction and muscle spasm, treating bowel disorders, treating respiratory disorders, treating locomotor activity or movement disorders, treating immune and inflammation disorders, regulating cell growth, use in pain management, use as a neuroprotective agent and the like.

It should be understood that contraceptive agents suitable for use in a combination product and/or therapy are not limited to oral contraceptives, but also include other commonly available contraceptives such as those that are administered transdermally, by injection or via implant.

Except as further specified, “combination product and/or therapy” means a pharmaceutical composition comprising a compound of formulae (I) or (Ia) in combination with one or more therapeutic agents. The dosages of the compound of formula (I) or (Ia) and the one or more therapeutic agents are adjusted when combined to achieve an effective amount.

The term “subject” as used herein, refers to a patient, which may be an animal, preferably a mammal, most preferably a human, which has been the object of treatment, observation or experiment and is at risk of (or susceptible to) developing a CB receptor mediated syndrome, disorder or disease.

The term “administering” is to be interpreted in accordance with the methods of the present invention. Such methods include therapeutically or prophylactically administering an effective amount of a composition or medicament of the present invention at different times during the course of a therapy or concurrently as a product in a combination form.

Prophylactic administration can occur prior to the manifestation of symptoms characteristic of a CB receptor mediated syndrome, disorder or disease such that the syndrome, disorder or disease is treated, ameliorated, prevented or otherwise delayed in its progression. The methods of the present invention are further to be understood as embracing all therapeutic or prophylactic treatment regimens used by those skilled in the art.

The term “effective amount” refers to that amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue system, animal or human, that is being sought by a researcher, veterinarian, medical doctor, or other clinician, which includes alleviation of the symptoms of the syndrome, disorder or disease being treated. The effective amount of a compound of the invention is from about 0.001 mg/kg/day to about 300 mg/kg/day.

Wherein the present invention is directed to the administration of a combination of a compound of formula (I) and an anticonvulsant or contraceptive agent, the term “effective amount” means that amount of the combination of agents taken together so that the combined effect elicits the desired biological or medicinal response.

As those skilled in the art will appreciate, the effective amounts of the components comprising the combination product may be independently optimized and combined to achieve a synergistic result whereby the pathology is reduced more than it would be if the components of the combination product were used alone.

For example, the effective amount of a combination product and/or therapy comprising administration of a compound of formula (I) and topiramate would be the amount of the compound of formula (I) and the amount of topiramate that when taken together or sequentially have a combined effect that is effective. Further, it will be recognized by one skilled in the art that in the case of combination product and/or therapy with an effective amount, as in the example above, the amount of the compound of formula (I) and/or the amount of the anticonvulsant (e.g., topiramate) individually may or may not be effective.

Wherein the present invention is directed to the administration of a combination product and/or therapy, the instant compound and the anticonvulsant or contraceptive agent may be co-administered by any suitable means, simultaneously, sequentially or in a single pharmaceutical composition. Where the instant compound(s) and the anticonvulsant or contraceptive agent components are administered separately, the number of dosages of each compound(s) given per day, may not necessarily be the same, e.g. where one compound may have a greater duration of activity, and will therefore, be administered less frequently.

The compound(s) of formula (I) and the anticonvulsant(s) or contraceptive agent(s) may be administered via the same or different routes of administration. The compound(s) of formula (I) and the anticonvulsant(s) or contraceptive agent(s) may be administered via the same or different routes of administration.

Suitable examples of methods of administration are orally, intravenous (iv), intramuscular (im), and subcutaneous (sc). Compounds may also be administrated directly to the nervous system including, but not limited to the intracerebral, intraventricular, intracerebroventricular, intrathecal, intracisternal, intraspinal and/or peri-spinal routes of administration by delivery via intracranial or intravertebral needles and/or catheters with or without pump devices.

The compound(s) of formula (I) and the anticonvulsant(s) or contraceptive agent(s) may be administered according to simultaneous or alternating regimens, at the same or different times during the course of the therapy, concurrently in divided or single forms.

Optimal dosages to be administered may be readily determined by those skilled in the art, and will vary with the particular compound used, the mode of administration, the strength of the preparation and the advancement of the disease condition. In addition, factors associated with the particular patient being treated, including patient's sex, age, weight, diet, time of administration and concomitant diseases, will result in the need to adjust dosages.

The term “CB receptor mediated syndrome disorder or disease” refers to syndromes, disorders or diseases associated with a biological response mediated by a CB receptor such that there is discomfort or decreased life expectancy to the organism.

Type II diabetes mellitus (non-insulin-dependent diabetes mellitus) is a metabolic disorder (i.e., a metabolism related syndrome, disorder or disease) in which glucose dysregulation and insulin resistance results in chronic, long-term medical complications for both adolescents and adults affecting the eyes, kidneys, nerves and blood vessels and can lead to blindness, end-stage renal disease, myocardial infarction or limb amputation and the like. Glucose dysregulation includes the inability to make sufficient insulin (abnormal insulin secretion) and the inability to effectively use insulin (resistance to insulin action in target organs and tissues). Individuals suffering from Type II diabetes mellitus have a relative insulin deficiency. That is, in such individuals, plasma insulin levels are normal to high in absolute terms, although they are lower than predicted for the level of plasma glucose that is present.

Type II diabetes mellitus is characterized by the following clinical signs or symptoms: persistently elevated plasma glucose concentration or hyperglycemia; polyuria; polydipsia and/or polyphagia; chronic microvascular complications such as retinopathy, nephropathy and neuropathy; and macrovascular complications such as hyperlipidemia and hypertension. These micro- and macro-vascular complications can lead to blindness, end-stage renal disease, limb amputation and myocardial infarction.

Insulin Resistance Syndrome (IRS) (also referred to as Syndrome X, Metabolic Syndrome or Metabolic Syndrome X) is a disorder that presents risk factors for the development of Type II diabetes and cardiovascular disease including glucose intolerance, hyperinsulinemia, insulin resistance, dyslipidemia (e.g. high triglycerides, low HDL-cholesterol and the like), hypertension and obesity.

Pharmaceutical Compositions

The term “composition” refers to a product comprising the specified ingredients in the specified amounts, as well as any product that results, directly or indirectly, from combinations of the specified ingredients in the specified amounts. The invention further comprises mixing one or more of the compounds of the invention and a pharmaceutically acceptable carrier; and, includes those compositions resulting from such a process. Contemplated processes include both traditional and modern pharmaceutical techniques.

Pharmaceutical compositions of the invention may, alternatively or in addition to a compound of formula (I) or (Ia), comprise a pharmaceutically acceptable salt of a compound of formula (I) or (Ia) or a prodrug or pharmaceutically active metabolite of such a compound or salt in admixture with a pharmaceutically acceptable carrier.

The term “medicament” refers to a product for use in treating, ameliorating or preventing a cannabinoid receptor mediated syndrome, disorder or disease.

“Pharmaceutically acceptable carrier” means molecular entities and compositions that are of sufficient purity and quality for use in the formulation of a composition of the invention and that, when appropriately administered to an animal or a human, do not produce an adverse, allergic, or other untoward reaction.

Since both clinical and veterinary uses are equally included within the scope of the present invention, a pharmaceutically acceptable formulation would include a composition or medicament formulation for either clinical or veterinary use.

The present invention includes a process for making the composition or medicament comprising mixing any of the instant compounds and a pharmaceutically acceptable carrier and include those compositions or medicaments resulting from such a process. Contemplated processes include both conventional and unconventional pharmaceutical techniques. Other examples include a composition or medicament comprising a mixture of at least two of the instant compounds in association with a pharmaceutically acceptable carrier.

The composition or medicament may be administered in a wide variety of dosage unit forms depending on the method of administration; wherein such methods include (without limitation) oral, sublingual, nasal (inhaled or insufflated), transdermal, rectal, vaginal, topical (with or without occlusion), intravenous (bolus or infusion) or for injection (intraperitoneally, subcutaneously, intramuscularly, intratumorally or parenterally) using a suitable dosage form well known to those of ordinary skill in the area of pharmaceutical administration. Accordingly, the term “dosage unit” or “dosage form” is alternatively used to refer to (without limitation) a tablet, pill, capsule, solution, syrup, elixir, emulsion, suspension, suppository, powder, granule or sterile solution, emulsion or suspension (for injection from an ampoule or using a device such as an auto-injector or for use as an aerosol, spray or drop). Furthermore, the composition may be provided in a form suitable for weekly or monthly administration (e.g. as an insoluble salt of the active compound (such as the decanoate salt) adapted to provide a depot preparation for intramuscular injection).

In preparing a dosage form, the principal active ingredient (such as a compound of the present invention or a pharmaceutically acceptable salt, racemate, enantiomer, or diastereomer thereof) is optionally mixed with one or more pharmaceutical carriers (such as a starch, sugar, diluent, granulating agent, lubricant, glidant, binder, disintegrating agent and the like), one or more inert pharmaceutical excipients (such as water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, syrup and the like), one or more conventional tableting ingredient (such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate, any of a variety of gums and the like) and a diluent (such as water and the like) to form a homogeneous composition (whereby the active ingredient is dispersed or suspended evenly throughout the mixture) which may be readily subdivided into dosage units containing equal amounts of a compound of the present invention.

Binders include, without limitation, starch, gelatin, natural sugars (such as glucose, beta-lactose and the like), corn sweeteners and natural and synthetic gums (such as acacia, tragacanth, sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like). Disintegrating agents include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum and the like.

Because of the ease of administration, tablets and capsules represent an advantageous oral dosage unit form, wherein solid pharmaceutical carriers are employed. If desired, tablets may be sugar or film coated or enteric-coated by standard techniques. Tablets may also be coated or otherwise compounded to provide a prolonged therapeutic effect. For example, the dosage form may comprise an inner dosage and an outer dosage component, whereby the outer component is in the form of an envelope over the inner component. The two components may further be separated by a layer, which resists disintegration in the stomach (such as an enteric layer) and permits the inner component to pass intact into the duodenum or a layer which delays or sustains release. A variety of enteric and nonenteric layer or coating materials may be used (such as polymeric acids, shellacs, acetyl alcohol, cellulose acetate and the like) or combinations thereof.

The liquid forms in which a compound of the present invention may be incorporated for oral administration include (without limitation), aqueous solutions, suitably flavored syrups, aqueous or oil suspensions (using a suitable synthetic or natural gum dispersing or suspending agent such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidone, gelatin and the like), flavored emulsions (using a suitable edible oil such as cottonseed oil, sesame oil, coconut oil, peanut oil and the like), elixirs and other similar liquid forms with a variety of pharmaceutically acceptable vehicles.

As is also known in the art, the compounds may alternatively be administered parenterally via injection. For parenteral administration, sterile solutions or injectable suspensions may be parenteral vehicles wherein appropriate liquid carriers, suspending agents and the like are employed. Sterile solutions are a preferred parenteral vehicle. Isotonic preparations that generally contain suitable preservatives are employed when intravenous administration is desired. A parenteral formulation may consist of the active ingredient dissolved in or mixed with an appropriate inert liquid carrier. Acceptable liquid carriers comprise aqueous solvents and the like and other optional ingredients for aiding solubility or preservation. Such aqueous solvents include sterile water, Ringer's solution or an isotonic aqueous saline solution. Alternatively, a sterile non-volatile oil may be employed as a solvent agent. Other optional ingredients include vegetable oils (such as peanut oil, cottonseed oil, sesame oil and the like), organic solvents (such as solketal, glycerol, formyl and the like), preservatives, isotonizers, solubilizers, stabilizers, pain-soothing agents and the like. A parenteral formulation is prepared by dissolving or suspending the active ingredient in the liquid carrier whereby the final dosage unit contains from 0.005 to 10% by weight of the active ingredient.

Compounds of the present invention may be administered intranasally using a suitable intranasal vehicle. Compounds of the present invention may be administered topically using a suitable topical transdermal vehicle or a transdermal patch. Administration via a transdermal delivery system requires a continuous rather than intermittent dosage regimen.

Compounds of the present invention may also be administered via a rapid dissolving or a slow release composition, wherein the composition includes a biodegradable rapid dissolving or slow release carrier (such as a polymer carrier and the like) and a compound of the invention. Rapid dissolving or slow release carriers are well known in the art and are used to form complexes that capture therein an active compound(s) and either rapidly or slowly degrade/dissolve in a suitable environment (e.g., aqueous, acidic, basic, etc). Such particles are useful because they degrade/dissolve in body fluids and release the active compound(s) therein. The particle size of a compound of the present invention, carrier or any excipient used in such a composition may be optimally adjusted using techniques known to those of ordinary skill in the art.

The present invention includes a composition of an instant compound or prodrug thereof present in a prophylactically or therapeutically effective amount necessary for symptomatic relief to a subject in need thereof.

A prophylactically or therapeutically effective amount of an instant compound or prodrug thereof may range from about 0.001 mg to about 1 g and may be constituted into any form suitable for the administration method and regimen selected for the subject.

Depending on the subject and disease to be treated, the prophylactically or therapeutically effective amount for a person of average body weight of about 70 kg per day may range from about 0.001 mg/kg to about 300 mg/kg; from about 0.01 mg/kg to about 200 mg/kg; from about 0.05 mg/kg to about 100 mg/kg; or, from about 0.1 mg/kg to about 50 mg/kg.

An optimal prophylactically or therapeutically effective amount and administration method and regimen may be readily determined by those skilled in the art, and will vary depending on factors associated with the particular patient being treated (age, weight, diet and time of administration), the severity of the condition being treated, the compound and dosage unit being employed, the mode of administration and the strength of the preparation.

Dosage unit(s) may be administered to achieve the therapeutically or prophylactically effective amount in a regimen of from about once per day to about 5 times per day. The preferred dosage unit for oral administration is a tablet containing 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 100, 150, 200, 250 or 500 mg of the active ingredient.

The terms used in describing the invention are commonly used and known to those skilled in the art. When used herein, the following abbreviations and formulae have the indicated meanings:

ABBREVIATION MEANING Cpd compound EDCI 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide DCM dichloromethane DMAP 4-dimethylaminopyridine EtOAc ethyl acetate Et₂O anhydrous ether K₂CO₃ potassium carbonate LDA lithium diisopropylamine LiHMDS or LHMDS lithium bis(trimethylsilyl)amide min(s)/hr(s) minute(s)/hour(s) N₂ nitrogen RT/rt/r.t. room temperature SOCl₂ thionyl chloride TEA or Et₃N triethylamine THF tetrahydrofuran

A solution of cycloheptanone Compound A1 (in a solvent such as THF and the like) is added dropwise to a reagent solution (such as LDA in a solvent such as anhydrous THF and the like) at −78° C. under an inert atmosphere (using a gas such as nitrogen and the like) and reacted, with stirring, at −78° C. for about 1 hr. A solution of Compound A2 (in a solvent such as anhydrous THF and the like, wherein Q-X_(y) represents a suitable reaction group and wherein certain portions of Q-X_(y) are incorporated into X₄R₄ as a product of the reaction) is added dropwise and the mixture is stirred for about 5 hrs, while warming to r.t., to provide Compound A3 after workup.

A solution of cycloheptanone Compound A3 (in a solvent such as THF and the like) is added dropwise to a reagent solution (such as LHMDS in a solvent such as anhydrous THF and the like) at −78° C. under an inert atmosphere and reacted, with stirring, at −78° C. for about 1 hr. A solution of Compound A4 (in a solvent such as anhydrous THF and the like) is added dropwise and the mixture is stirred for about 15 hrs, while warming to r.t., to provide Compound A5 after workup.

A reagent (such as K₂CO₃ and the like) and a substituted hydrazine mono or dihydrochloride Compound A6 are added to a solution of Compound A5 (in a solvent such as one or more of MeOH, EtOH, CH₂Cl₂ and the like) at a temperature of about 0° C. under an inert atmosphere. The mixture is stirred overnight, while warming to r.t., to provide Compound A7 after workup.

The X_(a)R_(a) substituent moiety on Compound A6 represents the possibility that, after isomer separation, the substituted amine group may be found either on the N¹ position as X₁R₁ or on the N² position as X₂R₂. Compound A7 represents a mixture of isomers, wherein a mixture of X₁R₁ and X₂R₂ isomers are present.

The hydrazine hydrochloride or dihydrochloride Compound A6 may be converted to the free base by methods known to those skilled in the art. In the examples of the present invention, the free base is prepared either in situ (as shown for illustrative purposes in this Scheme) or separately (then added to the reaction mixture) by reaction with K₂CO₃.

As illustrated in this Scheme, Compound A6 may also be further substituted with a variety of X_(a)R_(a) substituents (as previously defined herein). In many instances, the substituted hydrazine Compound A6 is commercially available. When not commercially available, a particularly substituted Compound A6 may be prepared by methods known to those skilled in the art.

More specifically, a halogenated X_(a)R_(a) substituent moiety is reacted with a hydrazine hydrate solution at reflux and used without further purification in place of Compound A6.

The Compound A7 isomeric mixture is separated via flash chromatography (eluted with a suitable solvent mixture such as about 10% to about 30% EtOAc and the like in hexane and the like) to provide a purified major isomer Compound A8 and a minor isomer Compound A9. The major isomer Compound A8 is substituted on the N¹ position with X₁R₁ (X₂R₂ is necessarily absent). The minor isomer Compound A9 is substituted on the N² position with X₂R₂ (wherein X₁R₁ is absent).

An acid (such as 3N HCl and the like) is added to a solution of Compound A8 (in a solvent such as acetone and the like) at about 0° C. under an inert atmosphere. The mixture is stirred for about 4 hrs, while warming to r.t., to provide Compound A10 after workup.

A reagent solution (such as 1M potassium tert-butoxide in a solvent such as THF and the like) is added dropwise to a solution of Compound A11 (in a solvent such as anhydrous THF and the like; wherein X_(b) represents a suitable reaction group and wherein certain portions of X_(b)R_(b) are incorporated into X₃R₃ as a product of the reaction). After about 45 mins, a solution of Compound A10 (in a solvent such as THF and the like) is added dropwise. The mixture is reacted for about 15 hrs, while warming to r.t., to provide Compound A12 after workup.

For purposes of this Scheme, X_(b)R_(b) is an alkylsulfonylamino moiety or an alkylcarbamoyl moiety each further substituted on the amino portion. In general, Compound A11 is commercially available. When not commercially available, a particularly substituted Compound A11 may be prepared by methods known to those skilled in the art.

A solution of Compound A10 (in a solvent such as acetone and the like) is added dropwise to a reagent solution (such as Jone's Reagent and the like) at about 0° C. under an inert atmosphere. The resulting suspension is stirred overnight, while warming to r.t., to provide Compound B1 after workup.

A reagent solution (such as one or more of EDCI, DMAP and the like) and Compound B2 (wherein X_(c) represents a suitable reaction group and wherein certain portions of X_(c)R_(c) are incorporated into X₃R₃ as a product of the reaction) are added to a solution of Compound B₁ (in a solvent such as CH₂CL₂ and the like) at about 0° C. under an inert atmosphere. The mixture is stirred for about 6 hrs, while warming to r.t., to provide Compound A12 after workup.

For purposes of this Scheme, X_(c) is an optionally substituted amino moiety, whereby the Compound A12 X₃R₃ substituent moiety incorporates the C(O) portion of the C³ substituent from Compound B1 and the amine portion from X_(c)R_(c).

A solution of Compound A3 (in a solvent such as Et₂O, THF and the like or a mixture thereof) is added dropwise to a reagent solution (such as LHMDS and the like in a solvent such as Et₂O or THF and the like or a mixture thereof) at −78° C. under an inert atmosphere and stirred at about −78° C. for about 40 mins. A solution of Compound C1 (in a solvent such as Et₂O and the like) is added dropwise and the mixture is stirred at about −78° C. for about 1 hr, then allowed to warm to r.t. over a period of about 2 hrs to yield Compound C2 after workup, as a crude product used without further purification in the next step.

Using the procedure of Scheme A and Compound C2 in place of Compound A5 provides Compound C3 after workup.

Using the procedure of Scheme A and Compound C3 in place of Compound A7, the Compound C3 isomeric mixture is separated via flash chromatography (eluted with a suitable solvent mixture such as 20% or 30% EtOAc:hexane and the like) to provide a major isomer Compound C4 and a minor isomer Compound C5.

The separated major isomer Compound C4 is treated with a reagent solution (such as a mixture of NaOH or LiOH in a solvent such as water, MeOH, THF and the like or a mixture thereof) and stirred overnight to provide Compound C6 after workup.

A reagent solution (such as SOCl₂ and the like in a solvent such as CH₂Cl₂ and the like) is added to Compound C6 at ambient temperature under an inert nitrogen atmosphere. The reaction mixture is stirred at reflux temperature for about 15 mins to provide Compound C7 after workup.

The mixture was stirred at r.t. overnight, then concentrated and acidified with 1N HCl (50 mL). The aqueous solution was extracted with EtOAc (100 mL) and the organic layer was washed with brine and dried over magnesium sulfate, then filtered and concentrated to give 1-(2,4-dichloro-phenyl)-8-(4-fluoro-benzylidene)-1,4,5,6,7,8-hexahydro-cycloheptapyrazole-3-carboxylic acid Compound 3g (0.73 g, 98%) as a yellow solid.

SOCl₂ (0.99 mL, 13.5 mmol) was added to a solution of Compound 3g (0.73 g, 1.69 mmol) in DCM (5 mL). The mixture was refluxed for 3 hrs, then concentrated under high vacuum to give 1-(2,4-dichloro-phenyl)-8-(4-fluoro-benzylidene)-1,4,5,6,7,8-hexahydro-cycloheptapyrazole-3-carbonyl chloride Compound 3h (0.70 g, 92%) as a yellow solid.

A mixture of (R)-(+)-α-methyl benzylamine Compound 3i (0.065 g, 0.54 mmol) and Et₃N (0.15 mL, 1.08 mmol) were added to a solution of Compound 3h (0.12 g, 0.27 mmol) was taken up in DCM (5 mL). The mixture was stirred at r.t. for 1 hr, then diluted with DCM and washed with 1N HCl. The organic layer was washed with water and dried over sodium sulfate, then filtered and concentrated. The resulting yellow residue was purified on silica gel column (using 20% EtOAc/Hexane) to give Compound 146 (0.12 g, 84%) as a pale yellow powder. MS m/z 534 (M+H⁺).

BIOLOGICAL EXAMPLES

The following examples illustrate that the compounds of the present invention are CB receptor modulators useful for treating, ameliorating or preventing a cannabinoid receptor mediated syndrome, disorder or disease in a subject in need thereof.

Example 1

Binding Assay for CB1 or CB2 Agonists or Inverse Agonists

The human CB1 and CB2 receptors were stably expressed in SK—N-MC cells transfected with pcDNA3 CB-1 (human) or pcDNA3 CB-2 (human). The cells were grown in T-180 cell culture flasks under standard cell culture conditions at 37° C. in a 5% CO₂ atmosphere. The cells were harvested by trysinization and homogenized in a homogenization buffer (10 mM Tris, 0.2 mM MgCl₂, 5 mM KCl, with protease inhibitors aprotinin, leupeptin, pepstatin A and bacitracin) and centrifuged (2000 g). The supernatant was then centrifuged in 2M sucrose (31,300 g) to produce a semi-purified membrane pellet. The pellet was resuspended in homogenization and stored at −80° C.

On the day of the assay, the pellet was thawed on ice and diluted in assay buffer (50 mM Tris-HCl, 5 mM MgCl₂, 2.5 mM EDTA, 0.5 mg/mL fatty acid free bovine serum albumin, pH 7.5). The diluted membrane pellet was added with buffer, either a test compound or vehicle standard and the radioligand [H]³⁺-CP-55,940 (0.2 nM) to the wells of a 96-well polypropylene plate. Non-specific binding was measured in wells containing WIN 55,212 (10 uM). The plate was covered and incubated for 90 minutes at 30° C. The contents were then aspirated onto a Packard Unifilter GF/C filter bottom plate prewet with 0.5% polyethyleneimine. The wells of the polypropylene plate were rinsed and aspirated seven times with a 0.9% saline-0.5% Tween 20 solution. The Unifilter plate was dried, a scintillation cocktail was added to each well and the counts representing binding were quantitated in a TopCount scintillation counter.

CB1 and CB2 Receptor Binding Results

Functional Cell-Based Assay for CB1 or CB2 Agonist and Inverse Agonist Effects on Intra-Cellular Adenylate Cyclase Activity

The CB1 and CB2 receptors are G-protein coupled receptors (GPCR), which influence cell function via the Gi-protein. These receptors modulate the activity of intracellular adenylate cyclase, which in turn produces the intracellular signal messenger cyclic-AMP (cAMP).

At baseline, or during non-ligand bound conditions, these receptors are constitutively active and tonically suppress adenylate cyclase activity. The binding of an agonist causes further receptor activation and produces additional suppression of adenylate cyclase activity. The binding of an inverse agonist inhibits the constitutive activity of the receptors and results in an increase in adenylate cyclase activity.

By monitoring intracellular adenylate cyclase activity, the ability of compounds to act as agonists or inverse agonists can be determined.

Assay

Test compounds were evaluated in SK—N-MC cells which, using standard transfection procedures, were stably transfected with human cDNA for pcDNA3-CRE β-gal and pcDNA3 CB1 receptor (human) or pcDNA3 CB2 receptor (human). By expressing CRE β-gal, the cells produced β-galactosidase in response to CRE promoter activation by cAMP. Cells expressing CRE β-gal and either the human CB1 or CB2 receptor will produce less β-galactosidase when treated with a CB1/CB2 agonist and will produce more β-galactosidase when treated with a CB1/CB2 inverse agonist.

Cell Growth

The cells were grown in 96-well plates under standard cell culture conditions at 37° C. in a 5% CO₂ atmosphere. After 3 days, the media was removed and a test compound in media (wherein the media was supplemented with 2 mM L-glutamine, 1M sodium pyruvate, 0.1% low fatty acid FBS (fetal bovine serum) and antibiotics) was added to the cell. The plates were incubated for 30 minutes at 37° C. and the plate cells were then treated with forskolin over a 4-6 hour period, then washed and lysed. The β-galactosidase activity was quantitated using commercially available kit reagents (Promega Corp. Madison, Wis.) and a Vmax Plate Reader (Molecular Devices, Inc).

CB1 Receptor Mediated Change in CRE β-Gal Expression

For cells expressing CRE β-gal and the CB1 receptor, CB1 agonists reduced β-galactosidase activity in a dose-dependent manner and CB1 inverse agonists increased β-galactosidase activity in a dose-dependent manner.

The change in β-galactosidase activity was determined by setting a vehicle treated cell's activity value at 100% and expressing the β-galactosidase activity measured in a corresponding compound treated cell as a percent of the vehicle treated cell activity.

CB1 Receptor Results

The EC₅₀ value for functional activity for compounds tested was calculated by linear regression and was obtained from studies in which varying compound concentrations were used.

Where an EC₅₀ value was not obtained for a test compound, the value shown (in %) represents change in functional activity and was obtained from a study in which one compound concentration was used.

The mice (9 per treatment group) were briefly anesthetized with ketamine/xylasine (Sigma, St. Louis, Mo.) and a solution of 0.5% OM in 30% ethanol (50 μL) was administered intracolonically (to a depth of 4 cm) via syringe (equipped with a ball-tipped 22 G needle).

A test compound was orally administered one day prior to colitis induction for assessing a prophylactic regimen or one day post-induction for assessing a therapeutic regimen. A test compound was orally administered daily thereafter. Two days after OM administration, the last test compound dose was administered.

Three days after OM administration, the animals were sacrificed. The colons were resected, examined for signs of inflammation, weighed after removing fecal contents and the length from the aboral end of the cecum to the anus was measured. The fecal contents were examined for signs of diarrhea. The distal colon between the 1^(st) and the 4^(th) centimeter was removed and placed in 10% neutral buffered formalin for histological analysis.

Macroscopic Observations and Criteria

The macroscopic observations of colon inflammation (a measure of colon damage), colon weight and length and stool consistency and appearance were assigned a score and used to evaluate colitis severity.

The four observation scores for each colon were combined, whereby a combined score of 0 represents a normal colon and a combined score of 15 represents a maximally affected colon. Statistical analyses were performed in Graphpad Prism 4.0 using ANOVA.

Dextran Sulfate Sodium (DSS) Induced Colitis Model

In the distal colon, the DSS colitis model is characterized by a discontinuous pattern of mucosal epithelial damage, infiltration of inflammatory cells (including macrophages, neutrophils and lymphocytes) into the mucosa and submucosa, decreased wet weight of the colon, shrinkage of the colon length and diarrhea (see, Blumberg R. S., Saubermann L. J. and Strober W., Animal models of mucosal inflammation and their relation to human inflammatory bowel disease, Current Opinion in Immunology, 1999, Vol. 11: 648-656; Egger B., Bajaj-Elliott M., MacDonald T.

Colitis Induction

Female Balb/c mice are provided with a solution of 5% DSS (45 kD molecular weight) in tap water ad libitum over a 7-day period. The DSS solution is replenished daily and the amount consumed is measured.

The mice are orally administered a test compound on the day of colitis induction and then daily thereafter. Six days after the initial DSS administration, the last test compound dose is administered.

Seven days after the initial DSS administration, the animals are sacrificed. The colons are resected, examined for signs of inflammation, weighed after removing fecal contents and the length from the aboral end of the cecum to the anus is measured. The fecal contents are examined for signs of diarrhea. The distal colon between the 1^(st) and the 4^(th) centimeter is removed and placed in 10% neutral buffered formalin for histological analysis.
